After the grisly discovery of Sheila's husband and the death of a suspect in custody, Cardinal and Delorme believe they may be looking for a professional killer. That killer, NEIL CUTHBERT, now appears to be stalking a new target, BARRY LEBLANC. Cardinal and Delorme attend the autopsy of the first victim and then his memorial, looking for potential suspects. Cardinal has suspicions about a man named TAJ ROY, but he has an alibi for the first murder. Delorme runs into her old boyfriend, JOSH McNIDER (season 1). As the detectives struggle to connect the dots, Neil abducts not Barry but his elderly mother, ADELE.
